Coolant Flange – 06A 121 132R (FEBI)

Description

Product Description

The 06A121132R Coolant Flange by Febi Bilstein is an OE‑quality replacement component used on select Volkswagen and Audi 4‑cylinder engines (commonly found on 1.8T applications, depending on model year and engine code). This housing serves as a key junction in the cooling system, providing secure hose connection points and proper coolant routing to help maintain stable engine operating temperature.

Because it’s exposed to constant heat cycling and pressurized coolant, the original plastic housing can become brittle, warp, or crack over time. This often leads to coolant leaks, dried coolant residue around the housing, low‑coolant warnings, and potential overheating. Replacing the worn unit with Febi 06A121132R restores a reliable seal and dependable cooling system performance.
